Show me a big corporation that is not "in league." They angle for whatever edge they can get, however they need to get it. Those who believe in liberty are unlikely to find much of it either Big Government OR Big Business. The modern world didn't happen with the cooperation, collaboration, and collusion of many people who ought to know better.
Small corporation, big corporation... doesn't matter.
"Corporations" shouldn't have a perspective, and they shouldn't endorse anything one way or another.
I had a firebrand conservative of a boss, who tossed money all over the place for various causes he supported or opposed. He owned the company. He would never use company money or company reputation to stand for or against anything though. He was not afraid to use his personal name to support or oppose something, but he never used his company's name to do so.
I respect his stance in regards to that.
I respect it even more for a publicly traded company (though his wasn't).
I think it's inherently wrong for corporate entities to engage in politicking. And if you sign a contract to represent a corporate entity in marketing campaigns, there may be clauses in the contract that you didn't expect.
I think Gunny found himself at odds with one of those clauses, and was more or less compelled by his own sense of honor to issue a (halfhearted) retraction of his statements.
